DVD-R media compatibility and write quality:

In these tests we will be using a Lite-On DH20A3P with firmware XV5H or our Lite-On DH20A3H with firmware YV64 along with CD-Speed to measure the disc quality. We will also be using the BenQ DW-1655 with firmware BCID or our Optiarc AD-7200A with firmware 1.Z2 along with CD-Speed for our read-back tests.

DVD-RW media compatibility and write quality:

For this test we used the same testing procedures as in our DVD-R tests.

Quality Scan with Lite-On DH203AH

TRT with BenQ DW-1655

PIE higher than the desired standard of 280 or lower at the start of the scan, however the PIF are acceptable and the Transfer Test curve is smooth.

Summary:

The ASUS DRW-20B1LT can write only one of our test media (Taiyo Yuden) at 20X; once again the write quality is quite good overall.
